Kenneth Pearce (Language and the Structure of Berkeley's World) argues that, for Berkeley, "bodies" are linguistic constructions built up from our phenomenal experience, and that causal talk, in everyday life and in physics, is an extension of that sort of operation. But Berkeley does not therefore dismiss such talk. The reason is twofold:
- First of all, to model things this way is useful: it helps us "in the pursuit of happiness, which is the ultimate end and design... that sets rational agents at work" (204).
- But these ideas are also true, in an important sense: they reflect the underlying reality of "the regular ordering of ideas instituted by God, i.e., the linguistic or grammatical structure of the divine language of nature. Our talk about bodies aims to capture the lexicon of this language, and our talk about causes, laws, and forces aims to capture its syntax" (204).
